MACHINE FOR SECURING WIRE T0 FRAMES.

To all whom it may concern:

Be it known that I, GEORGE W. DARLIN- TON, a citizen of the UnitedStates, residing at Los Angeles, in the county of Lo s Angeles and Stateof California, have invented new and useful Improvements in Machines forSecuring Wire to Frames, of which the following is a specification.

This invention relates to improvements in machines for securingscreening to frames, and it particularly relates to the securing ofwire'fabric or screening to frames for closing various openings such aswindows, doors or the like.

It is an object of the invention to provide a machine with suitablepressure devices for holding the screening and the frame to which it isapplied in proper position in relation to each other and also wit-hmeans for guiding and forcing securing ribs, ratan or the like ingrooves in the framing so as to bind and hold the screening in position.

It is also an object of the invention to provide curved pressure meansfor shaping and inserting the edges of the wire screen'- ing and forcinginto position the binding reed. ratan or other strip at the corners ofthe screens.

It is also an object of the invention to provide means for feeding thewire screening and the securing reeds or ratans into place beneath thepressure devices so that the proper amount of screeningwill be engagedby the ratan, reeds or other strips, fo facilitating the binding of theedges.

tional view taken upon the line 7--7 of Fig. 6. Fig. 8 is an enlargedperspective view of the presser foot employed for directing and holdingthe screening and rata-n in position for being forced into the groove ofthe framing. Fig. 9 is a detail perspective view taken upon the line 99of Fig. 7. Fig. 10 is an enlarged fragmentary sectional View takenthrough a portion of a frame, and showing the edge of a wire screensecured in a groove in the frame by reed or' ratan.

The features of the invention will now be more fully described,reference being had to the accompanying drawing.

In said drawing 10 indicates a frame which is secured to a standard orsupport 11 preferably suspended from above so as not to interfere withthe work passing beneath the apparatus. The said standard is preferablyof triangular shape in cross-section as shown in Fig. 2, and the frame10 is bolted or otherwise secured to one of its faces. The said frame isprovided with outwardly extending bracket portions 12 and 13 in which ismovably mounted a plunger rod 14.. The upper end of said rod projectsabove the bracket 12 and is bifurcated at 15 so as to facilitate apivotal attachment to a lever 16 which is mounted upon the top of theframe 10. The said lever 16 is fulcrunied upon an arm 17 projecting fromthe upper end of said frame 10, and its inner end is provided with aslot 18 for engaging a pin 19 which passes over a bifurcated upper endof the plunger rod 14. The plunger rod is provided with a stop in theform of a nut 20 between which and the bracket 12 is arranged a coiledspring 21 which normally tends to force the said plunger 14 downwardlyand into engagement with the work.

The lower end of the plunger 1-1 is provided with a head 22 whichcarries a bracket 23, the arms of which extend upwardly so as to braceand slide upon the bracket 13. The head 22 is provided with a downwardlyextending bifurcated portion in the lower part of which is journaledpressure rollers 24: and 25 and a rod or ratan inserting roller 26. Theroller 24, which is adapted to engage the wider portion of the framingto which a wire screening is to be secured, is journaled upon a shaft 27which finds a bearing at 28 in one of the downwardly projecting portionsof the said head 22. The outer end of the shaft 27 is provided with acrank 29 by which it may be turned. The inner end of the shaft 27projects beyond the roller 24 and is provided with a cam portion 30 uponwhich is revolubly mounted the said groove roller 26. By turning theshaft 27 the eccentricity of the roller 26 with respect to the roller 24may be varied and the depth to which the said grooved roller 26 willforce the ratan or reed in the groove of the frame will be controlled bythe position of the said cam 30.

The shaft 27 is adapted to be clamped in any adjusted position by meansof a set screw 31 which extends through a threaded recess 32 formed inthe head 22, and is adapted to bear against the periphery of the saidshaft 27 as clearly shown in Fig. 7 of the drawing. The said screw 31 isloosened when the shaft 27 with the cam 30 is to be adjusted, and thecrank 29 is turned until the grooved wheel 26 projects at the lower edgeof the pulley 24 the desired distance for forcing the ratan into thegroove of the screen framing after which the set screw 31 is tightened.

The pressure roll 25 is usually made narrower than the roll 24, thoughof course it may be made of various widths within the spirit of theinvention. The said roller 25 is movably mounted upon the inner end of ashort shaft 33 which is secured to a block 34. The said block 34 ismounted so as to 'plate 36 secured to the lower end of one of thebifurcated portions of the said head 22 as illustrated in Fig. 9. Inorder to hold and adjust the roller 25 in the desired relation to theother rolls 24 and 26, the block '34 is connected with a rod or shaft 37having a bearing in the adjacent portion of the head 22 and having aswivel engagement at 38 with the said block 34. The said shaft 37 isprovided with a cam portion 39 adapted to engage a pin 40 and force thesaid pin against one of the walls of the recess 35 and thus bind theblock 34 in adjusted position. By turning the shaft 37 so that thereduced side of the cam portion 39 will come opposite the pin 40, thesaid pin will move inwardly and release the block 34 so that the samemay be adjusted longitudinally of the said recess 35. By moving theblock longitudinally of said recess, the roll 25 may be advanced-orplaced to the rear of the rolls 24 and 26 or may be positioned exactlyopposite the same. The axis of the said roller 25 is preferably upon thesame horizontal plane as the axis of the saidroller 24.

The head 22 upon the opposite side thereof from the roller 25 isprovided with a yielding presser foot 41 which is carried by springpressed rods 42 which extend upwardly into vertical bearings formed inthe head 22 and into an enlarged recess 43 also formed in said head 22.The rods 23 are normally pressed downwardly by a spring 44 which ismounted in the recess 43 and bears against a shoulder 45 formed uponeach of said rods 42. The upper end of each of said springs is seatedagainst the upper end of the recess 43, the bolts 42 being limited intheir downward movement by nuts 46 applied to their upper ends.

The presser foot 41 has secured to it a guide plate 47 which is providedwith means for holding and directing the wire screening beneath the roll25 and also with means for directing the ratan or reeds beneath the roll26. The said plate 47 is secured to the pressure foot 41 by means of abolt 48 which extends through an aperture in the presser foot 41, and isclamped in position by a nut 49 applied to the upper end of said bolt48. The nut 49 is accommodated when in its uppermost position byrecesses 50 formed in the under edge of the adjacent part of said head22. By securing the said plate 47 to the said presser foot 41 by asingle bolt, the plate may be set at slightly different angles forinsuring the proper feeding of the wire screen to the securing pressurerolls. This is found especially useful as the wire sometimes shows atendency to stretch more in one direction than in the other, and suchunevenness or tendency can the plate 47 is formed with an inclined andslightly curved surface as 51, adapted to more or less closely lit thecontour of the roll 24 as will be understood by reference to Fig. 8. Theinner edge of the plate 47 is provided with a vertically arranged edgeplate 52, the front end of which is curved downwardly and forwardly at53 so as to also fit the periphery of the roller 24. The front edge ofthe said plate 47 is recessed at 54, and an adjustable plate 55 ismounted in said recess, a set screw 56 which extends through a slot 57in the plate 47, holding the said plate 55 in its adjusted positions.The

plate 55 is designed to be adjusted laterally Fig. 8. The plate 55 maybe adjusted laterally to control the extent to which the re duced part58 projects beyond the edge plate 52, and the adjustment of said plateis a matter of importance in securing the proper guiding of the screenwhich is being operated upon. The wire screening which is to be securedto the frames is also guided in being presented to the rolls 24, 25 and26 by means of laterally projecting rollers 60 and 61, the saidscreening being usually guided between the said rollers, passingdownwardly over the rollers 61 and forwardly beneath the roller 60 asalso indicated in dotted lines in Fig. 8.

In order to tend to feed the edge of the screening toward and againstthe plate 52, inclined feed rollers 62 and 63 are also provided, onebeing arranged immediately above the other, and the screen being passedbetween them. The upper roller 63 is preferably carried by a shaft 64which projects from a pivoted block 65. The said block 65 is pivotallymounted upon the plate 47, and a spring 66 mounted upon the extendedpivot pin 67 of said block normally tends to force the block 65 with theroller 63 downwardly. The said block 65 with the roller 63 can be liftedat any time for inserting the screening beneath the same for feeding thesaid screening into the machine. The said plate 4L7 also carries a ratanguide plate 68 which isadjustably clamped upon the said plate 17 asclearly shown in Fig. 8.

Y The said guide device carries an inclined groove portion 69 which iscurved clownwardly and forwardly so as to lead the ratan accurately intoposition over the edge of the wire screening and beneath the groovedroll 26. The block 65 may be made to operate automatically if desired,the said block being connected by means of a cord 70 with the upper endof one of the pins 42 so that when said head rises, the cable 70 will becaused to lift the block 65 and the roller 63 so that a new piece ofwire screening may be inserted beneath the same.

Below the head 22 is a work supporting roller mechanism made up of aframing 71 in which are journaled roller-s7 2, there preferably being aplurality of such rollers so that the work is movably supported beneaththe head and its presser foot when the screening is being appliedthereto.

The said standard 11 also carries an additional presser device which ismounted upon a plate 73 which is secured to the said standard 11 and isprovided with upper and lower brackets 7-l and 75 respectively. Movablymounted in said brackets are plunger rods 76 and 77 preferably arrangedparallel with each other and adapted to move one against the other. Thelower ends of the said plunger rods are provided with work engagingheads as 78 and 7 9. The head 78 is provided with a projecting noseportion 80 of a proper shape to fit into the corner of the screen justinside the ratan. The said head portion 79 also carries a guide strip 81spaced from said nose portion 80 and lying parallel therewith so as toform a slot through which a ratan driving slide may be passed. The saidratan driving slide 82 is carried by the head 78. By reason of themounting of the plunger bars 76 and 77 the head 79 may first descend andrest upon the work after which the head 78 will fall, the slide 82passing downwardly through the slot inside the plate 81. and engagingthe ratan for forcing it into the groove of the framing to which thewire screening is to be secured. The relative positions of said partsand their location when operating upon the work can be readilyunderstood by reference to Fig. 4 of the drawing. The lower edge of theslide 82 is preferably grooved as indicated at 83 so that the said slidewill properly fit upon the ratan or reed for forcing it into the grooveof the frame. As stated heretofore the heads 78 and 79 follow each otherin their action. To secure this action, two springs surround the saidplungers, one of said springs 81 being made stifl'er and stronger thanthe other, or the spring 85. The plunger 76 carries a collar 86 whichbears upon the upper end of the said spring 84. The lower end of thespring 82L bears upon a collar 87 which is rigidly secured to theplunger 77. The spring tends to lift both of the plungers 76 and 77,while the spring 8st under the action of the collar 86 will insure aproper depression of both of the said plunger-s.

The upper end of the plunger 76 is bifurcated at 88, and is pivotallyconnected with an operating lever 89. One end of said lever 89 isconnected by links 90 with a fulcrumed arm 91 projecting from thebrackets 74:. The plunger 77 is made slightly shorter than the plunger76 so that it will not be engaged by the lever 89. By depressing thelever 89 the plunger 76 begins to descend carrying the collar 86downwardly with it. The spring 84 will cause the collar 87 to force thehead 7%) into engagement with the work, first holding the screening inposition at the corner of the framing to which it is to be applied. Thelighter spring 85 will then yield so that the plunger 76 may beforceddownwardly carrying the head 78 and the slide 82. The slide 82will be carried downwardly far enough to force the ratan into the grooveof the framing carrying with it the edge of the screening as shown inFig. l and thus securing the corner of the framing in position as shownin Figs. el, 5 and 10. The framing 92 to which the screening is to beattached is provided with a groove 93 to receive the edge of the saidscreening 94, and the securing of ratan or reed 95.

In operating the machine, the framing to which the wire screening is tobe fastened is first placed upon the bed 96 of the machine, one of therolls of the said framing being extended beneath the head 22. The wirescreening has its edge portion inserted beneath the roller 63 and it isthen drawn downwardly between the rollers 60 and 61 and underneath thegage plate 58. The ratan or reed to secure the screen in place is thendrawn from any suitable supply, and the end thereof passes downwardlythrough the groove plate 69. The screen frame with the wire screening isthen carried forwardly beneath the plate 47 and the pressure rolls 2st,25 and 26 are pressed tightly upon the screen and framing so that as thematerial is advanced beneath the rollers, the grooved roller 26 willforce the ratan and the edge of the wire screening beneath it, tightlyinto the groove 93 of the said framing. Upon reaching the corner of theframing, the work is shifted upon the bed 96 so as to bring the saidcorner beneath the head 79 after which the lever 89 is depressed, thehead 79 holding the screening in position while the slide 92 descendsand forces the ratan in a curved position opposite the nuts 80, into thecurved portion of the groove 98, thus securing the screening and ratanin the position shown in Fig. 5. The work is then again shifted to bringit beneath the rolls 24:, 25, and 26 for securing the next side of thewire screening in, place. The work is then continued untilt-he edge ofthe screening has been secured entirely around the same.

As above intimated the rollers 62 and 63 set in an incline with respectto the edge plate 52 tend to feed the screening against the said plate52. The said rollers 62 and 68 as well as the rollers 60 and 61 areusually slightly roughened or serrated on their peripheral surfaces tobetter engage the wire screening if the wire screening is found to tendvto draw outwardly from over the groove 98, the roller 25 is advancedslightly in front of the other rollers to insure clamping the screeningin position and prevent its pulling away. If however, the screeningtendsto pull in the other direction the roller 25 may be pulledbackwardly opposite the other rollers or arranged to the rear of thenext of said rollers. The said rollers may be readily and quicklyadjusted to accomplish their work. The eccentric mounting of the ratanengaging roller 26 makes it possible to force the ratan the proper depthinto the groove 93, the adjustment being in accordance with the depth ofsaid groove and the thickness of the ratan being used.

The adjustment of the plate 55 with its projecting flange 58 controlsthe positioning of the ratan with respect to the edge of the screen.Then the plate 58 projects a considerable distance beyond the plate 52,a

greater margin of screening will be carried downwardly into the groove93 of the ratan 95. When it is not desired to have the screen extend sofar into the groove, the plate 58 is drawn inwardly and the ratan liesnear the edge of the screen and does not carry so much of it in thegroove.
